We studied the effect of antiflammin-2 (AF-2) on adhesion molecule expression by HL-60 cells and endothelial (ECV304) cells stimulated by lipopolysaccharides (LPSs), and on leukocyte-endothelial cell interaction in an in vitro coculture system. The action of AF-2 on prostanoid production in these experimental conditions was also tested. LPS increased the adhesion molecule expression, such as ly...

Adhesion molecules play a role in the inflammation and pathogenesis of vascular diseases. In 13 patients with primary Raynaud's phenomenon, 19 with Raynaud's phenomenon associated with connective tissue disease, and 16 control subjects, we measured plasma levels of soluble forms of intercellular adhesion molecule-1, vascular cell adhesion molecule-1, E-selectin, and von Willebrand factor. Patie...

Nervous system dysfunction may occur in as many as 80% of patients with Systemic Lupus Erythematous (SLE) at some point in their disease course. Upregulation of adhesion molecules has been linked to acute SLE-related disease activity and chronic damage. We evaluated the relationship between soluble adhesion molecule levels and neuropsychiatric lupus (NPSLE) manifestations using the American Col...

Human melanoma cell lines that express high constitutive levels of the metastasis-associated marker intercellular adhesion molecule 1 (ICAM-1) were found to secrete interleukin 1 (IL-1) in vitro. Experiments with neutralizing antibodies showed that this cytokine was responsible for their expression of ICAM-1 but not that of two other progression/metastasis markers, Muc-18 and Gp IIb/IIIa. The I...

Cadherins are expressed in tissue-restricted patterns and typically mediate homophilic adhesion. Cadherins also mediate lymphocyte adhesion, providing the opportunity for lymphocyte attachment to parenchymal cells. The best characterized example of lymphocyte adhesion to a tissue-specific cell adhesion molecule, as opposed to a vascular endothelial adhesion molecule, is the interaction between ...

The receptors that mediate monocyte adhesion to cytokine-stimulated endothelial monolayers were assessed using a nonstatic (rotating) cell-attachment assay. In this system, leukocyte adhesion molecule-1 (LAM-1) (L-selectin) mediated a major portion (87 +/- 15% at 37 degrees C) of monocyte attachment to activated endothelium. mAb blocking of endothelial leukocyte adhesion molecule-1 (41% inhibit...

Background. Adhesion molecules are known to influence postoperative organ function, they are hardly involved in the inflammatory response following the ischemia-reperfusion injury. We sought to investigate the potency of small interfering RNAs to suppress adhesion molecule expression in human pulmonary microvascular endothelial cells. Methods. Human lung microvascular endothelial cells were tra...

To facilitate tumor colonization by adoptively transferred cells of the immune system, we created a chimeric cell adhesion molecule that mediates tumor-specific homing by binding to the integrin avb3 on angiogenic endothelial cells. A high-affinity cell adhesion molecule for integrin avb3 was generated by fusing the disintegrin kistrin to the transmembrane adhesion molecule CD31/PECAM-1. This c...

The XT-1-molecule, an adhesion-related differentiation antigen of male mouse germ cells, is a 34 000 Mr glycoprotein with major charge isomer at pI 5.1 and is an integral component of the cell membrane. On large late pachytene spermatocyte, the molecule is present at a concentration of 2.5 X 10(3) molecules micron-2, which approximates HLA/ABC concentration on lymphocytes. By comparing the reac...
